The House of the Heron has long stood on the hills of Old Providence, a structure of unknown origin, a watchtower to a sprawling land, a grave to gods of old and monsters of myth. In the land of Meiying, fable and gods once meant life: but now there is plague in the air, famine in streets, and the spirit of the people is dying. Poisoned by the venom of the Yan dynasty and a prohibition of storytelling, the fledgling Emperor of Yan, Huang Lei makes his ascent to the throne - his corrupt eyes set on the House of the Heron, and the ailing Empress who guards it. Intending to quash the last hallmark of fable from Meiying and absorb Old Providence into the new Meiying, the Emperor begins his march towards the House: but the House will not give in that easily to the rapacity of men - and the choices made by a guard, an Emperor and a scroll-smuggling scribe could cost Meiying it all.
